JSON to XML Converter

Convert JSON to well-formed XML. Runs in your browser; nothing is uploaded.

How to convert JSON to XML

  1. Paste your JSON into Input (JSON), open a .json file, or click Sample.
  2. Choose your Indent style (2 spaces, 4 spaces, tab, or minified), customize the Root and Item element names if needed, and toggle XML declaration.
  3. Click Convert to XML, then copy or download the well-formed .xml document.

How JSON properties, arrays and attributes map to XML 1.0

The JSON document is wrapped in a single root element (<root> by default) and turned into well-formed XML 1.0.

  • Attributes and text content: object keys starting with @ (for example "@id": "b1") become attributes on the enclosing XML element (id="b1"), and "#text" becomes the element's inner text.
  • Arrays: an array inside an object repeats that property's element for each item; a top-level or nested array wraps each entry in the configured item element (<item> by default).
  • Empty and null values: null values and empty objects are emitted as concise self-closing tags (such as <field/>).
  • Safe tag names & escaping: keys containing spaces, leading digits, or symbols are sanitized into legal XML names, and special characters (&, <, >, ") are automatically escaped.

Example: JSON with attributes and arrays to XML

Input JSON:

{
  "@version": "1.0",
  "book": [
    { "@id": "b1", "title": "The Pragmatic Programmer", "price": 42.5 },
    { "@id": "b2", "title": "Clean Code & Design", "price": 38 }
  ]
}

Converted XML output:

<?xml version="1.0" encoding="UTF-8"?>
<root version="1.0">
  <book id="b1">
    <title>The Pragmatic Programmer</title>
    <price>42.5</price>
  </book>
  <book id="b2">
    <title>Clean Code &amp; Design</title>
    <price>38</price>
  </book>
</root>

Frequently asked questions

How do I create XML attributes and element text from JSON?
Prefix any JSON property key with @ (for example "@id": "b1") to emit it as an attribute on the enclosing XML element (id="b1"). When an element has both attributes and text content, place the text under the "#text" key.
What happens if a JSON key contains spaces or starts with a number?
XML 1.0 tag names cannot contain spaces or begin with a digit. The converter automatically sanitizes invalid characters into underscores and prepends an underscore to leading digits so the output is always well-formed XML.
Can I convert the generated XML back into JSON?
Yes. The XML to JSON Converter uses the same @attribute and #text conventions, allowing clean round-trip conversions between JSON and XML.
